Transmission of prioritized information in the proximity of reference signals

Abstract

Transmission of information in a wireless network is performed by allocating a channel from a transmitter to a receiver. The channel has at least one time slot with each time slot having a plurality of symbols. Each slot contains at least one reference symbol (RS). As information becomes available for transmission, it is classified as prioritized information (PI) and other information. Digital samples are produced using an element of prioritized information. One or more priority symbols are generated using the digital samples. Other symbols are generated using the other data. Priority symbols are transmitted on the channel in a manner that separation of priority symbol(s) and a reference symbol does not exceed a time duration of one symbol. The other symbols are transmitted in available locations.
